build(java.net.Socket sock,
java.lang.String canonicalName,
java.security.KeyPair keyPair,
Authorizer authorizer,
Credentials credentials,
long livenessTimeDiff,
boolean isClient,
SbEventHandler eventHandler)
Here's the problem: for secure class loading, we need to get
Authorizer and the partner's credentials (or an
AuthorizationMonitor) to the SbSocketIoLayer so that it can
give it to the ContainerClassLoader that will load classes as
they are read from the ContainerObjectInputStream that is
generated from the Socket.
